Apple TV 5.2 is now available and addresses the following:

Apple TV
Available for:  Apple TV 2nd generation and later
Impact:  A user-mode process may be able to access the first page of
kernel memory
Description:  The kernel has checks to validate that the user-mode
pointer and length passed to the copyin and copyout functions would
not result in a user-mode process being able to directly access

smaller than one page. This issue was addressed through additional
validation of the arguments to copyin and copyout.
